We use these on our interior doors when leaving the pet's home alone for 24 hours or more. These keep the doors from being closed by the pets and prevent them from being trapped in a room away from food/water/litter.
Note: We always have someone stop by the house daily to check on the pets/food/water. We are just paranoid:)
Our doors are just under 1 3/8" thick, 1.35 to be exact. The “door keeps” should fit doors a little thinner and thicker, but I have not tested them on other doors.
Print with PETG, layer height of choice. I don't recall, but I may have printed these with 100% infill, although should still be okay with anything above 20%.
The author marked this model as their own original creation.
